What it is and why choose it
ALEXSEAL Epoxy Primer Reducer Slow (R4032) is a halogen-free blend of organic solvents specially formulated as a slow evaporating reducer for ALEXSEAL epoxy primers, including ALEXSEAL Finish Primer 442. It is designed for professional, industrial serial painting where controlled flow, improved leveling and extended wet edge are required, particularly at higher ambient temperatures.
Main features
- Slow evaporation profile – helps maintain a wet film longer, reducing dry spray and improving flow and leveling in warm conditions.
- Optimized for epoxy primers – recommended as a slow reducer for ALEXSEAL Finish Primer 442 and other compatible ALEXSEAL epoxy primer systems.
- Consistent application properties – supports uniform atomization, film build and surface appearance when spraying.
- Halogen-free organic solvent mixture – chemical nature specified as a mixture of organic solvents, halogen-free.
- Professional-grade product – intended for industrial serial coating applications with appropriate safety and handling controls.

Section 8 – Personal protective measures
Exposure controls
- Ensure good general and/or local exhaust ventilation to keep solvent vapour concentrations below applicable occupational exposure limits.
- If ventilation is insufficient to maintain airborne concentrations below limit values, use suitable respiratory protection.
Individual protection equipment
- Eye/face protection: Wear safety goggles to protect against solvent splashes.
- Hand protection:
- Use chemical-resistant protective gloves complying with EN 374.
- Recommended materials for short-term contact (splash protection): nitrile rubber or neoprene.
- Minimum material thickness: > 0.4 mm.
- Breakthrough time: > 480 minutes.
- Skin and body protection: Wear antistatic protective clothing made from natural fibres (cotton) or heat-resistant synthetic fibres. Clean skin thoroughly after contact.
- Respiratory protection: When workplace exposure limits are exceeded, wear an approved respirator. Recommended: half-mask with combined filter (minimum class A1P2) or air-fed respirator.
General protective measures
- Do not eat, drink or smoke while using the product.
- Avoid contact with skin, eyes and clothing.
- Avoid inhalation of vapours, spray mist and sanding dust.
- During spray operations inside a spray booth, operators present should wear compressed air-fed respiratory protection until solvent vapour concentrations fall below exposure limits.
